This invention relates to engraving machines, and has particular reference to such machines wherein the pattern or model is usually composed of a plurality of lines of copy letters or characters arranged in predetermined relative juxtaposition to deiine a predetermined pattern or model which is traced by a stylus, the movement of the stylus being transmitted toa cutting tool forreproduction of the pattern or design on the work to be engraved. v

The stylus and cutting tool are usually arranged on a pantograph, whereby the reproduction may be made in any desired predetermined scale.

The invention is directed particularly to the provision of a copy character holder for engraving machines provided with means for rapidly and accurately assembling the copy characters in predetermined relative juxtaposition to deiine the predetermined pattern.

A further object of the invention is to provide a copy character holder comprising a channeled member having secured thereto means for assembling a plurality of lines of copy characters in predetermined relative juxtaposition and having means for rapidly and easily securing the assembly to a copy characterplate, and for rapidly removing the same from the plate and substituting any other desired predetermined copy characters thereon.

A further object of the invention is to provide a copy base plate provided with the assembly described above, adapted to be secured to theengraving machine standard in predetermined transversely offset position so that the copy character plate may be secured to the standard in more than one position relative to the engraving machine cutter for presenting diierent positions relative to the cutter.

In the drawings, Fig. 1 shows a copy character holder I0 embodying my invention and comprising, as shown in Figs. 1 and 3, an H-shaped memberconsisting of the bar II having a pair of end members I2 secured thereto by any suitable means, such as by rivets I3 passing through the bar II and members I2. The members I2 are provided with a plurality of longitudinal slots vIl adapted to freely receive the depending studs I5 which are preferably riveted or otherwise integrally secured to the channeled members I6, the lower ends of studs I5 being preferably threaded as shown in Fig. 5 for engagement by correspondingly threaded nuts Il by means of which the channeled members I6 may be frictionally secured to the end members `I2 in predetermined spaced relation thereto. To facilitate positioning of the members I6 on the endr members I2 of bar II, the members I'are provided on the undersurfaces ofthe ends thereot` with transverse recesses Ia dening'shoulders lIb for abutting engagement with end members I2 as shown in Fig.5. The bar II, as shown cross-sectionally in Fig. 7, is provided with a pair of upstanding longitudinal Walls I8, which are preferably recessed and denne a longitudinal channel IIa for the reception of correspondingly designed latching members I9, which are usedto secure the copy character letters 20 in the channel IIa, said copy character letters 2d being of similar cross-section to the latching members I9. Members I6 have similarly defined channels Ic; the copy characters 20 are postionedwithin the channels of members II and I6 either in abutting relation as in Fig. 1 in bar II, or in spaced relation as in Fig. 1 in the members I6; in the latter case, the copy characters 20 are maintained in the desired predeterminedv relationwithin the members I6 by spacing elements 2I of the desired width and of the same general cross-section as the copy characters 20. The latching members I9 are preferably threaded for the reception of the threaded bolts 22, the lower ends 23 of which I are adapted to bear against the channels as in Fig. 7 so that said latching members may besecurely latched therein holding the copy characis secured whereby a portion 211 of the base plate 1 Will overlie the standard S either onthe fullline.

this means, the location or juxtaposition ofithe K copy character holder, on the engraving machine" and therefor relative to the engraving machine ing the clamp 32 up against the bevelled longitudinal edge 30 of the plate 25.

Although I have shown in the drawings, as one illustration of the invention, copy characters secured within the channels of the members Il and I6, the term copy character is not used in a limiting sense as the invention is adapted for use in the assembly of any copy pattern comprising a plurality of lines of matter to be traced and reproduced on engraving machines.

Having thus described my invention, what I vclaim is new and desire to secure by Letters Patent is:

A 1 A copy Acharacter holder for engraving machines kcomprising a bar for holding copy characters said bar being provided with a pair of upstanding longitudinal walls recessed to denne a longitudinal channel, copy characters positioned cutter thereon may be readily varied as. desired. Y y

The base plate is preferably secured to the standard S by means of. .av bolt 28v :passing throughH aperture .25. of said base` plate and threaded into the standard| as .indicated inFig. 6.

The lower longitudinal veclgesf2=9 .of the base plate are bevelled as indicated at 33 in Figures4 and 5, said bevelled edge Sibeing adaptedto be irictionallyV engaged by. the-i complementarily` bevelled` edge 31| of the clamp member 32 of the copy character holder l0. YThe clamp member 32 is provided with an aperture` by lmeans of which thev clamp may be freely arranged on'the stud 34- Xed to and dependingfrom one of the end members |.2 of the bar H, said stud being preferably threaded at its lower end as indicated in Fig. 4 for the engagement by the threadednut 35. By this means clamp` member 32 may be drawn up against the bevelled longitudinal edge 30 of the plate* 25 to secure the holder I0 and the'various parts Xed thereto to thebase plate By the arrangement described, I have provided ay novel means for assembling aA copy character pattern with .the lines of copy characters ar.- ranged inthe members Il and `IS in predetermined relation juxtaposition. It willy be obvious that any number of members, I6 adapted to be accommodated by end members l2 may be added to the. assembly in the manner described above andillustrated in the drawings. f

IfL desired', a. plurality ofY spacing members 35 may be positioned intermediatathe: adjacently disposed Walls of` the members H and I6 for the purpose of facilitating therapid andaccurate positioning of saidmembersl before the tightening of the nuts l1 thereof.` If desired. one of themembers .I2 of bar I0 may .beprovided on the undersuriace thereof, with a recessedA portion 31 for the partial receptionA of the clamp-member` -32 as shown in Fig..4. --It will be -noted Vthat I ly positioned on the plate 25 with the end memin said channel, means engaging the channel to displaceably secure the copy character thereto and' a pair of end members secured to said bar in spaced parallel relation, said end members being adapted to engage the edges o f a base plate of an engraving machine, and clamping meansY carried byone of said end members adapted tov engage said base plate for clamping thev copy character holder thereto.
